Product Description


customized WCU parts W70Cu30 tungsten copper alloy solid shaft rod
WCu alloys are used where the combination of high heat resistance, high electrical and/or thermal conductivity, and low thermal
expansion are needed. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As
contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical
discharge machining and electrochemical machining.

The CuW75 alloy, with 75% of tungsten, is widely used in chip carriers, substrates, flanges and frames for power semiconductor
devices. The high thermal conductivity of copper together with the low thermal expansion of tungsten allows thermal expansion
matching to silicorn, gallium arsenide, and some ceramics. Other materials for this applications are CuMo alloy, AlSiC, and
Dymalloy.

Alloy with 70-90% of tungsten is used in liners of some specialty shaped charges. The penetration is enhanced by factor 1.3
against copper for homogeneous steel target, as both the density and the break-up time are increased. Tungsten powder based shaped
charge liners are especially suitable for oil well completion. Other ductile metals can be used as binder in place of copper as
well. Graphite can be added as lubricant to the powder.
